DOCSIS CHECK –
REGISTRATION, THROUGHPUT, PING/TRACEROUTE and PACKET QUALITY
 REGISTRATION will display the configuration file if the
CM MAC has been provisioned.
 The THROUGHPUT, PING/TRACEROUTE and PACKET
QUALITY functions will be greyed out if the CM MAC is
not provisioned. Or if an un-provisioned MAC address is
selected in CONFIGURE-> SELECT DOCSIS SERVICE
PLAN.
 The throughput test sends a file upstream to a server.
The server then sends the file back to the meter. Since
the file size is known and the time it takes to download
the file is known, the meter can then calculate the
downstream speed. The same is done for the upstream.
 The PING/TRACEROUTE function can be configured to
send configurable ping packets to a destination. A
TRACEROUTE test can also be done to configurable
destinations.
 The packet quality test sends ping packets to the CMTS
and the meter counts any lost packets, measures latency,
(round trip time) and measures maximum jitter. (variations
in latency)
